Abstract
Design and analysis of a printed prototype of an S-shape slotted patch antenna for 16.8 GHz Ku band application is proposed in this paper. The proposed miniaturized S-shape patch antenna has been designed and analyzed by using market available Ansoft high frequency electromagnetic simulator and fabricated on a printed circuit board. The measured -10 db return loss bandwidth ranges from 15.35 GHz to 19.65 GHz (25.59 %) with achieved gain of 6.2 dBi at the resonant frequency 16.8 GHz. A radiation efficiency of 88.2 % and 80 (320 degrees-40 degrees) 3 dB beam width has been testified. The symmetric and almost steady radiation pattern of the proposed antenna has been made suitable for the frequency range from 15.35 GHz to 19.65 GHz. Furthermore, the current distribution over the radiating patch is examined and a parametric study of the ground plane size has been conducted in this study.
